It is quite possible that Tux3 will get to incremental and online fsck before
Ext4 does. (There you go, Ted, that is a challenge.) There is no question that
this is something that every viable, modern filesystem must do, and no,
scrubbing does not cut the mustard. We need to be able to detect errors on the
filesystem, perhaps due to blocks going bad, or heaven forbid, bugs, then
report them to the user and *fix* them on command without taking the volume
offline. If that seems hard, it is. But it simply has to be done.

Because online fsck is awesome.

(Also if i understood correctly the layout should work wonders with spinning media. And also result in wear-leveling on ssd:s)

Errors happen, bugs happen. Its the nature of software. You do the best you can, but a bug will always find a way in. Plus hardware fails as Rahul pointed out. Thats why its not a "We have the perfect filesystem. Zero errors!" approach. Its a "This is reality. Shit happens. We need to protect against the shit." approach

This file system have a lot of potentiality i hope that everything work the best until, finally, will be ready.

I believe that would have the potential to become an enterprise file system something that is not ext4 (since important features such as snapshots are not present) but remained far lighter (so usable even on old machine with few resource) respect Btrfs (that is a sort of an elephant so we need not wonder that despite the support it receives isn't never ready as default file system and anyway require too much resource).
